The Earth's lithospheric movements and geomorphology serve as a crucial lens for understanding the dynamic behavior of the planet's interior. Surface observations offer key insights into mantle convection patterns across space and time, while seismic data provides a contemporary snapshot, and they constitute important constraints for theoretical models. Geological records contribute invaluable spatial-temporal information on the historical vertical motion of the lithosphere. Geomorphology of volcanoes and volcanic features contains inherent information on the wide range of geologic and geomorphic processes that construct and degrade them. These collective observations facilitate addressing still-standing debates, for instance on mechanisms (i.e. active margin-related versus mantle plume-related),, amalgamation/collision timings, and the evolution of biosphere pathways leading to the formation of Gondwana.

This session offers a comprehensive examination of Earth's dynamic processes since Gondwana formation, encompassing geophysical, geochemical, geomorphological, seismological, stratigraphic, and volcanic aspects, along with investigations in submarine and subglacial environments, and numerical modeling. It presents a platform for diverse presenters and attendees, spanning various disciplines, demographics, and career stages, to actively participate in addressing exciting and emerging challenges in Earth science.
